    摘要: A medical electrical lead with a tip-ring assembly optimized to resist damage during extraction. The lead includes an elongated plastic tube and at least two elongated conductors mounted in the plastic tube. A tip-ring assembly is mounted to the distal end of the tube, the tip-ring assembly including a ring electrode coupled to one of the conductors, a tip electrode located distal to the ring electrode and coupled to another of the conductors and two molded plastic components separately fabricated of a plastic harder than the plastic tube, adhered to one another and together defining a circumferential groove in which the ring electrode is located and mechanically coupled to the tip electrode. The tip electrode may be provided with a proximally extending electrode shank covered by a tine sleeve which is fabricated of a plastic softer than the molded plastic components and is adhered to more distally located molded plastic component. The more distally located molded plastic component preferably overlaps the electrode shank to provide a stronger structure.

    摘要: Curves and dynamic shapes are imparted in distal segments of medical instruments e.g., catheters, through use of a temperature-activated actuator coupled to distal segment of the instrument body. The actuator comprises includes members extending side-by-side in substantially a common plane and configured to move in opposite directions when independently activated. A first heating device is coupled to a first actuator member and configured to deliver thermal energy to the first actuator member to activate the first actuator member and cause the first actuator member to move the distal segment in a first direction. A second heating device is coupled to a second actuator member and configured to deliver thermal energy to the second actuator member to activate the second actuator member and cause the second actuator member to move the distal segment in a second direction opposed to the first direction.
